Thread-topic:	[PATCH] Fix gdtr access on vmxassist

Hi, Keir:
        the gdtr information in oldctx is an address for guest, not for
vmxassist. When access descriptor on guest gdt, we need to go through
guest page table if guest enable paging. This error may happen if guest
enable PE/PG in one instruction.
 
This patch fix this issue.
